FILE CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,'71l=, dated May13, 1884:.

No model.)

To all whom it may concern:

Be it known that I, CHARLES VoGnL, of Fort Lee, in the county of Bergenand State of New Jersey, have invented an Improvement in File- CuttingMachines, of which the following is a specification.

This invention is made for rendering the file-cutting mechanismavailable for various kinds of work, and for producing the most perfectwork and with great rapidity.

I place the file upon an anvil or bed and pro vide a chisel or cuttersustained in a sliding stock and raised by a cam. The parts areadjustable, so that only one cam is used for dilferent depths of out,there being an adjustable rest upon the file-blank that determines theposition of the cutter-stock with relation to the cam, the blow anddepth of out being in creased in proportion to the height that the camis allowed to lift the cutter and stock. The cutter is moved laterallyas the cutting progresses, so that the file'blank is acted upon by adifferent portion of the cutting-edge each blow, and the entire width ofthe out ting-edge, or nearly so, is made. use of, and the cutterrequires less sharpening and is worn uniformly. The cutter is raised byatreadle, and the feed thrown off simultaneously, so that thecutter-stock and cutter-head can be moved back without touching thefile-blank, and there is astop to limit the backward move ment, so thatthe cutting is commenced with accuracy at the proper distance from thepoint of the file-blank.

In the drawings, Figure 1 is an elevation of the machine. Fig. 2 showsthe back end of the cam-shaft and the joint for the cutterhead arm. Fig.3 is the lifter-slide detached. Fig. 4. is a section at a: x of Fig. 1,in larger size. Fig. 5 shows the cutter-stock in section. Fig. 6 is asectional plan at 1 yof Fig. 5. Fig.

at the head of which is the file-bed 0, upon which the file-blank a islaid; and it is held by any suitably gage and fingers, as usual infileoutting machines.

In the drawings I have represented the cutter as operating upon one edgeof a prismatic file-blank. This is usually done in making files iorsharpening saws. Vhen cutting the side of the prismatic blank, a holderwith a V shaped groove is employed, as usual to hold the file-blank withits upper side parallel with the top of the file-bed 0.

Upon the bed A there are the bearings b, within which are received thetubular journals (6 of a yoke, D, that is provided with aradiusbar, E,which with the yoke can be swung back and forth upon its tubularjournals Within the bearings b,- and there is a set-screw, c, passingthrough the yoke D and forming a stop against the bed, to limit thebackward movement of the bar E and the cutter carried by it. At theupper end of this bar E there is a compound joint, F, connecting the armG to the bar E. This joint F is made with a pivot-stud, (1, running downinto a hole in the upper end of the radius-bar E, (see dotted lines,Fig. 2,) and the arm G is provided with a circular arm, cl, extendinglaterally from its rear end, through which the j0int-bolt a passes. (Seethe detached plan view, Fig. 10.) This arm G carries at its front endthe cutterhead H, with the cutter-stock and cutter here inafterdescribed. It also has a weight, G, by which the parts are steadied, andthe file is held down by a rest, (1, at the cutter-head that pressesupon the file a. It will nowbe understood that the cutter-head H can bemoved lengthwise of the file-blank, in consequence of the bar E and itsyoke turning in the bearings b, and the arm G, turning at itsjoint withthe joint-block F; and there can be more or less of horizontal swingingmotion given to the arm Gr and the cutter head, because the pivot of thejoint-block F can turn in its socket at the upper end of the radius-barE.

The main shaft 70 is in the tubular journals of the yoke D, and it isprovided with fast and loose pulleys for the driving-belt, and with thepulley k for the feeding apparatus, and with the pulley k for the belth, that extends up to the pulley h at the end of 4 a shaft, 71?, that iswithin the arm G, said arm being tubular or having bearings for suchshaft; and there is a cam, i, at the end of the shaft it next to .thecutter-stock. This cam is revolved at a uniform speed, or nearly so, andit acts upon the toe-piece Z of the cutter-stock to raise the same, andas it clears the toe the spring Z projects the cutter-stock and cutterdown with the required. momentum to cut the file.

The cutter-stock P is made to slide within the cutter-head H. The lowerpart of the stock is ribbed at" each edge, to slide in the head-piecesh", that project downwardly from the cutter-head, and are held togetherby the screw a, so as to prevent any looseness, but allow freedom of endmotion to the out ter-stoek. The cutter m itself is a blade with astraight sharp edge held in the jaw-shaped end of the cutter-stock by aclamp-screw, 3. (See Fig. 5.)

At the side of the cutter-head H there is a side bar, N, which has anL-shaped head, through which the screw m passes, to adjust the bearingfor the spring Z, so as to regulate the force of said spring, and theconsequent power with which it projects the cutter-stock and cutteragainst the file-blank a. This bar Nis in a groove at the side of thehead H, and it is held rigidly in its place by a bolt, to, that is madeas seen by dotted lines'in Fig. 4:. The smaller part of the bolt passesthrough a holein N, and screws into the head H. The larger part of thebolt acts to clamp N to place, and it also forms a bolt in a slottedslide-lifter, if. The nut on this bolt it holds the slide a in place,but allows it to be raised and lowered, as hereinafter set forth.

I remark that it is preferable to make the upper part of thecutter-stock P circular and with an annular shoulder, against which thelower end of the spring Z rests.

At the lower part of the side bar, N, the rest 6 is fastened. This restis .adjustable by the slot and clamping-screw 4. This rest extends outover the file-blank, and by it the cutter-head H-and arm G aresupported, and the weight of the cutter-head and arm upon such restserves to hold the file-blank down upon its bed. 1

It is to be borne in mind that under ordinary circumstances thecutter-stock P and cutterm are unsupp orted, except by the file-blankand the arm G, and other parts carried by it can be raised and loweredsufficiently for adj ustment without lifting the cutter. If the screw 4is loosened and the cutter-head raised and the rest c again clamped tothe'bar N, the shaft h and cam 13 will be raised toward the toe Z,-henee the cam, as it revolves, will lift the cutter a greater distance,and it falls a corresponding distance, giving a heavier blow and makinga deeper cut in the file-blank. If the cutter-head is lowered in itsrelation to the rest 6, the reverse action takes place, as the shaft andcam are moved downwardly from the toe Z,- hence the cam raises thecutter a less distance, and a slighter blow and cut is given by saidcutter It is to be understood that the cam i continues to revolve, andthat the cutter drops as the cam clears the toe Z, but that the distancethe cutter is raised and dropped varies according to the adjustment ofthe rest 0, because the shaft and cam are changed, as aforesaid, intheir relation to the toe. The cutter, in falling, strikes on the blankand there remains until again raised, and the extent of the liftingmotion depends upon the position of the shaft and cam to the toe. Bythis means one cam is made to give more or less stroke to the cutter,and the depth of cut is regulated to the greatest accuracy, and the outcan be very fine or very deep, as desired.

From the pulley k a belt leads to the pulley L upon a shaft, 0, that issupported by the column B, and provided at the other end with a pinion,0, which gives rotation to the feed gear-wheel p; and upon the axisof 1) there is a grooved feed-pulley, q. The feed-bar 1" is jointed atthe back end to the radius-barE, and it lies upon the feed-pulley q. Iprefer to make this feed-bar triangular, or approximately so 5 but itmay be round or polygonal, and the pulley q should have a groove withinclined sides. It might, however, be a rounding groove. There is alever, It, and weight S, the lever'being pivoted at s, and carrying aroller, 25, above the feed-bar 1", so that the weight will press thefeed-bar firmly into contact with the feed-pulley q. As the feed-pulleyis rotated, it will move the feed-bar, radiusbar, and

in the column B, for the shaft 0, said bushing being clamped by a nut atthe end, so that it may be partially rotated and then firmly secured.This eccentric bushing 0 allows for the shaft 0 being brought nearer toor farther from the wheel 12, so that the pinion 0 may be changed, andthe relative sizes and speeds of the pinion and feed-wheel 1) may bevaried to change the distance between the cuts on the file-blank.

In order to stop the feed, I make use of a treadle, T, and vertical barU, having a pin, 6, below the lever B, so that when the treadle isdepressed the lever R will be raised and the feed-bar relieved frompressure by the roller 16; hence the feed will be stopped and theradius-bar, cutter-head, and cutter can be moved back or forward byhand, as may be necessary. In order, however, to prevent injury to thecut file, and to stop the cutting, it is necessary simultaneously tolift the cutter-head and cutter and hold them above the file-blank, outof the way of the same, so that one blank canbe moved and anotherintroduced, or the blank be turned over. To effect this the rod U iscontinued 011 through the bed 0 to the lifterbar a, that is provided atthe bottom of the groove a in the file-bed O, and there is a lifter, a",in a groove in the side of the bar N, which lifter is held in place by anut on a bolt, if, said bolt passing loosely through a slot in N andscrewing into head H, so that said lifter is free to slide verticallythe length of said slot 5 and there is a pivoted block, a, at the bottomend of this lifter, running in the groove u, and resting upon the bar a.This groove might be parallel to the file; but it is preferably at aninclination, as shown in Fig. 6. Upon this lifter a there is a finger,a, that passes out beneath the lower end of the cutter -stock. WVhen thetreadle T is depressed, the rod U raises the lifter-bar u bodily in thegroove a, (the two being firmly connected,) and in so doing the lifter ais raised, said lifter sliding in its groove in the bar N, and thefinger a first lifts the cutter-stock and raises the cutter off thefile-blank. The movement thus given is sufficient to raise the toe, sothat the cam t does not act upon it; hence the cutter is not moved bythe continued rotation of said cam. The finger it moves in a slot in thelower part of the bar N, and upon the finger reaching the upper end ofthe slot, said finger lifts the bar N, rest (2, and cutter-head, at thesame time that it lifts and supports the cutter-stock and cutter. Bythis arrangement of mechanism the shafts and pulleys continue to revolvewhile the cutter is raised and the file-blank changed or turned; butneither the feed nor the cutter cam is in active operation; henceunnecessary Wear is prevented.

As before remarked, the groove a is at an inclination to the file;hence, the block a" remaining in that groove whether the bar a is raisedor not, the parts are guided as moved back or forth, and when themachine is in action cutting the file-blank the whole cutter-head andcutter are moved laterally, so that the cutting-edge of the cutter ismoved in its relative position to the blank, and when the cutting iscommenced the blank is beneath the cutter, near one end of thecutting-edge, and when the cutting is finished thefile-blank is beneaththe cuttingedge, near the other end'thereof, thus insuring uniformity ofwear and causing the cutting-edge to last longer without sharpening.

In place of the groove a,a rib might be provided, or the bar u mightform such rib, the block it, having side pieces like a fork, passingdown at each side of the bar a,- but the form shown is preferred.
